Character can't walk on navmesh since 4.18

Hello I migrate my project from 4.17 to 4.18
My character can’t walk now, I see that under my character it’s orange now, it was green before, but i don’t know why and how to disable it.


You may have the “Can Affect Navigation” option turned on for your capsule. Try to turn it off and see whether this fixes it.

it’s not orange now, but still don’t move

That could be a different issue. How do you move your character? Can you show the Blueprints?
